WARNING
Battery posts, terminals, and related accessories contain
lead and lead compounds, chemicals known to the State
of California to cause cancer and reproductive harm.
Wash hands after handling.
WARNING
Charge batteries in an open well ventilated area, away
from sparks and flames. Unplug charger before connect-
ing or disconnecting from battery. Wear protective cloth-
ing and use insulated tools.
WARNING
Avoid skin and clothing contact with battery acid.
Always wear eye protection when checking the battery,
acid can cause serious injury to skin and eyes. If contact
occurs, flush area with clean water and call physician
immediately. Acid will also damage clothing.
Do not drink the battery electrolyte.
Do not allow open flame near the battery when charging.
Hydrogen gas forms inside the battery. This gas is both
toxic and flammable and may cause an explosion if
exposed to flame. Always remove the negative ground
first and replace it last.
Do not overfill battery.
Electrolyte may overflow and damage paint, wiring or
structure. When cleaning the battery, use soap and water.
Be careful not to get soap and water into the battery.
Clean the battery terminals with a solution of four parts
water and one part baking soda when they become cor-
roded.
WARNING
Shorts caused by battery terminals or metal tools touch-
ing metal mower components can cause sparks. Sparks
can cause a battery gas explosion which will result in per-
sonal injury.
• Prevent the battery terminals from touching any
metal mower parts when removing or installing the
battery.
• Do not allow metal tools to short between the bat-
tery terminals and metal mower parts.

Incorrect battery cable routing could cause damage to the
mower and battery cables. This can cause sparks which
can cause a battery gas explosion which will result in per-
sonal injury.
• Always disconnect the negative (black) battery
cable(s) before disconnecting the positive (red)
cable(s).
• Always connect the positive (red) battery cable(s)
before connecting the negative (black) cable(s).

Hydraulic System

The TrimStar mower is equipped with two transaxles.
IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic system.
The hydraulic expansion tank is located behind the left rear
corner of the engine. Figure 4-2
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more often if
system appears to be leaking or otherwise malfunctioning.
Fluid level should be at the "Full Cold" line on the expansion
tank. Use only SAE 20W50 SL service motor oil.
Initial system oil and filter change must be after the first 75
hours of use or 1 year whichever comes first. Thereafter, replace
filter and oil in each transaxle every 2 years or 200 hours,
whichever comes first. NOTE: The filter guard must be
removed to access filter.
Each transaxle's filter is located per Figure 4-3. A standard oil
filter wrench is used to change filter, threads are right handed.
Use a Hustler ® approved filter element only.
When washing the mower, direct the spray away (espe-
cially if using a power washer) from the transaxle's seals
to prevent water intrusion and to ensure component per-
formance.
